TIG Welder - Argon Quick-Disconnect

# Quick-Disconnect Adaptor for Argon Gas Fitting ## Thread Adapter for TIG Welder ### Background My TIG welder initially lacked a quick-disconnect feature for the Argon gas fitting, requiring manual connection and disconnection of a brass UNF 5/8x18 fitting to switch between TIG torches. ### Solution I acquired a quick disconnect from eBay (type TBC) and designed this thread adapter using OpenSCAD. The welder features a UNF 5/8x18 thread, while the quick-disconnect boasts an M12x1 thread. To accommodate your specific needs, simply edit the variables in the SCAD file. ### Printing I printed the adaptor with a layer height of 0.15mm and 100% infill. ### Fitting Instructions For leak-free connections, I highly recommend applying Teflon tape to both threads. Given that this is located on the torch-side, there's negligible pressure (Argon gas) on the adaptor. However, I do not suggest using this adapter for high-pressure fittings. To ensure a secure seal, apply soapy water and inspect for leaks.
